When I hear people talk about "true love" what comes to my mind is the kind of head-over-heals type of love that people describe after meeting someone who is their soulmate. Two people who consider themselves to be each other's soulmate will come to feel that they are the best match for each other. Sometimes a couple will have so much in common or be so much alike in terms of personality and taste that, after meeting, they can't help but just be in love with each other. They seem to "know" that they're "meant for each other" and what they feel is what they describe as a unique bond or a kind of love and adoration that they have never felt for another person and can't imagine feeling it towards anyone else. This is what I think many people often mean by "true love".
I have never felt this kind of affection. I have known at least one person, possibly even more (meaning my memory would fail me for additional examples), who described a "love-at-first-sight" meeting with someone who became her future husband. It was mutual with her husband. The first time they set eyes on each other, there was an instant attraction, and they were unbelievably well-matched and were the perfect couple.
I personally wish for a "love-at-first-sight" kind of meeting with some lovely lady. I don't know how frequently it occurs. I remember my parents telling me when they first met, they didn't ever think that they would fall in love with each other. My parents thought each other to be obnoxious but once they got to know each other, they developed feelings for each other. On the other hand, my brother Dan and his wife had a sort of "attraction-at-first-sight" when they were introduced by mutual friends.
I really wouldn't want to spend months or years getting to know a person before developing feelings for her. It's not impossible for it to happen but the idea of taking months or years to get to know a person is a major turn off. I would love to fall in love with someone at first sight and have it be mutual. That's just me.
